abstract #1501: Is hormone replacement therapy (HRT) following risk-reducing salpingo-oophorectomy (RRSO) in BRCA1 (B1)- and BRCA2 (B2)-mutation carriers associated with an increased risk of breast cancer? | 2011 ASCO Annual Meeting Abstracts
University of Pennsylvania School of Medicine - Women with BRCA mutations can take hormone-replacement therapy safely after ovary removal
Women with the BRCA1 or BRCA2 gene mutations, which are linked to a very high risk of breast and ovarian cancer, can safely take hormone-replacement therapy (HRT) to mitigate menopausal symptoms after surgical removal of their ovaries, according to new research from the Perelman School of Medicine at the University of Pennsylvania which will be presented Monday, June 6 during the American Society for Clinical Oncology's annual meeting (Abstract #1501). Results of the prospective study indicated that women with BRCA mutations who had their ovaries removed and took short-term HRT had a decrease in the risk of developing breast cancer...............
Domchek says some of the confusion about the role of HRT in cancer risk elevation comes from the fact that the risks and benefits associated with HRT depend on the population of women studied. In this group of women – who have BRCA1/2 mutations and who have had their ovaries removed while they are quite young – HRT should be discussed and considered an option for treating menopausal symptoms. "People want to make hormone replacement therapy evil, so they can say 'Don't do it,'" she says. "But there isn't one simple answer. The devil is in the details of the studies."
By contrast, Penn researchers and their collaborators in the PROSE consortium have shown definitively that oophorectomy reduces ovarian and breast cancer incidence in these women, and reduces their mortality due to those cancers. But paying attention to the role that hormone depletion following preventive oophorectomy plays in women's future health (blogger's note: eg. cardiovascular) is also important............"
"...PF-01367338 would be developed by Clovis as both a monotherapy and in combination with chemotherapeutic agents for the potential treatment of selected cancer patients.
PF-01367338 is currently in a Phase 1 clinical trial examining the maximum tolerated dose of oral PF-01367338 that can be combined with intravenous platinum chemotherapy in the treatment of solid tumors.
Clovis was founded by former executives of Pharmion Corp., which was acquired by Celgene Corporation in 2008. The company is headquartered in Boulder, Colorado, and has additional offices in San Francisco and London."
For ovarian (epithelial) cancer, the committee recommended:
- Physical exam and review of symptoms: Every three months for two years, followed by increasing intervals
- Pap test: Not indicated
- CA-125: Optional
- Radiographic imaging: Insufficient data to support routine use
- Suspected recurrence: CT and/or PET, plus CA-125
- Physical exam and review of symptoms: Every two to four months for two years, then every six months or annually depending on histology
- Serum tumor markers: Every two to four months for two years, then every six months for sex-cord stromal tumors but no longer indicated for germ-cell tumors
- Radiographic imaging: Generally, not indicated or data lacking to support routine use
- Suspected recurrence: CT and tumor markers
Moreover, a survey of primary care providers showed that respondents believed transition of oncology patients could be improved with individualized patient summaries, guidelines for surveillance, and expedited referral for suspected recurrence, the committee members noted.
"Thus, the provision of up-to-date information and the education of both patients and physicians are mandatory," they wrote.
Point out that this report indicates that there is very little evidence that either routine cytologic procedures or imaging are sufficiently useful to detect ovarian and endometrial cancer recurrence and alter response rates to salvage therapy.
Note that this report suggests that the most effective method to detect recurrences is a taking a thorough history, performing a detailed physical examination, and educating patients about relevant symptoms."

Targeted testing offers treatment hope for ovarian cancer patients
Women with ovarian cancer could be helped by a new test that identifies the specific type of tumour they have, a conference will hear this week.
Researchers at the University of Edinburgh hope this improved diagnosis will help doctors to personalise treatment programmes so that patients receive the most effective drugs.
The Edinburgh team worked with scientists from Ireland to identify six subgroups of the disease, each of which had a different genetic signature.
To do this, they analysed tissue samples from more than 350 ovarian cancer patients and compared this information with the patients' medical records.
The results show how genetic profiling of ovarian cancers might predict a person's response to drug treatments.
Researchers say the development may be particularly helpful for women with an aggressive form of ovarian cancer, which is typically caught late by current diagnostic tests.
This type of aggressive – or 'high grade' – cancer can respond well to a recently-developed drug that targets the blood supply of the cancer cells. (blogger's note - it is not clear from this press release if this is specific to serous cell type)
The team hopes that by identifying the women with this type of cancer at the earliest opportunity, they could use the drug more effectively and help to improve survival rates.
The findings will be presented at the American Society of Clinical Oncology (ASCO) conference, being held in Chicago this week.
Dr Charlie Gourley of the University of Edinburgh, who led the study, said: "This research shows that by conducting a detailed analysis of the genes of ovarian cancers we may be able to identify those patients who will respond well to new drug treatments. This could bring valuable improvements in survival rates for the disease and would help us to personalise a patient's care to ensure the greatest possible success."
Ovarian cancer is the fifth most common cancer in women, with around 6,800 women being diagnosed every year in the UK.
Of these, nearly two-thirds will not live beyond five years of their diagnosis.
Chemotherapy and surgery can be effective treatments, but women could have a greater chance of surviving the disease if it is identified earlier on.
The findings will be presented at ASCO on Saturday 4th June.

Expert Opinion: The Therapeutic Target Database: an Internet resource for the primary targets of approved, clinical trial and experimental drugs
".....Increasing numbers of proteins, nucleic acids and other molecular entities have been explored as therapeutic targets.
A challenge in drug discovery is to decide which targets to pursue from an increasing pool of potential targets, given the fact that few innovative targets have made it to the approval list each year.
Knowledge of existing drug targets (both approved and within clinical trials) is highly useful for facilitating target discovery, selection, exploration and tool development. The Therapeutic Target Database (TTD) has been developed and updated to provide information on 358 successful targets, 251 clinical trial targets and 1254 research targets in addition to 1511 approved drugs, 1118 clinical trials drugs and 2331 experimental drugs linked to their primary targets (3257 drugs with available structure data).
This review briefly describes the TTD database and illustrates how its data can be explored for facilitating target and drug searches, the study of the mechanism of multi-target drugs and the development of in silico target discovery tools."
Evidence Updates including professional commentaries: Safety of Probiotics to Reduce Risk and Prevent or Treat Disease.
"....Existing studies primarily examined Lactobacillus alone or in combination with other genera, often Bifidobacterium.
Few studies directly compared the safety among different intervention or participant characteristics. Indirect comparisons indicated that effects of delivery vehicles (e.g., yogurt, dairy) should be investigated further.
Case studies suggested that participants with compromised health are most likely to experience adverse events associated with probiotics. However, RCTs in medium-risk and critically ill participants did not report a statistically significantly increased risk of adverse events compared to control group participants.
Conclusions. There is a lack of assessment and systematic reporting of adverse events in probiotic intervention studies, and interventions are poorly documented. The available evidence in RCTs does not indicate an increased risk; however, rare adverse events are difficult to assess, and despite the substantial number of publications, the current literature is not well equipped to answer questions on the safety of probiotic interventions with confidence."
Evidence Updates including professional commentaries - : Acupuncture: does it alleviate pain and are there serious risks? A review of reviews.
Acupuncture is commonly used for pain control, but doubts about its effectiveness and safety remain.
This review was aimed at critically evaluating systematic reviews of acupuncture as a treatment of pain and at summarizing reports of serious adverse effects published since 2000. Literature searches were carried out in 11 databases without language restrictions. Systematic reviews were considered for the evaluation of effectiveness and case series or case reports for summarizing adverse events. Data were extracted according to predefined criteria. Fifty-seven systematic reviews met the inclusion criteria. Four were of excellent methodological quality. Numerous contradictions and caveats emerged. Unanimously positive conclusions from more than one high-quality systematic review existed only for neck pain. Ninety-five cases of severe adverse effects including 5 fatalities were included. Pneumothorax and infections were the most frequently reported adverse effects.
In conclusion, numerous systematic reviews have generated little truly convincing evidence that acupuncture is effective in reducing pain. Serious adverse effects continue to be reported. Numerous reviews have produced little convincing evidence that acupuncture is effective in reducing pain.
Serious adverse events, including deaths, continue to be reported.
EvidenceUpdates + professional commentaries (numerous): Calcium supplements with or without vitamin D and risk of cardiovascular events: reanalysis of the Women`s Health Initiative limited access dataset and meta-analysis
OBJECTIVES: To investigate the effects of personal calcium supplement use on cardiovascular risk in the Women`s Health Initiative Calcium/Vitamin D Supplementation Study (WHI CaD Study), using the WHI dataset, and to update the recent meta-analysis of calcium supplements and cardiovascular risk.
DESIGN: Reanalysis of WHI CaD Study limited access dataset and incorporation in meta-analysis with eight other studies.........
Conclusions: Calcium supplements with or without vitamin D modestly increase the risk of cardiovascular events, especially myocardial infarction, a finding obscured in the WHI CaD Study by the widespread use of personal calcium supplements. A reassessment of the role of calcium supplements in osteoporosis management is warranted.
Expert Opinion on Investigational Drugs -Investigational antibody drug conjugates for solid tumors Summary (Pfizer)
Note: access to the full article is payer-per-view ($$$)
"Despite the progress made in the past 20 years in understanding the molecular events leading to the formation of cancer, the success of targeted antitumor agents in solid tumors has lagged behind the scientific discoveries. The most difficult to treat patient segments are those with refractory solid tumors, resistant to standard chemotherapy, and novel therapeutic compounds with improved therapeutic indexes are needed. Antibody drug conjugates (ADCs) are poised to become an important class of cancer therapeutics, as evidenced by the promising objective response rates when administered as single agents to chemorefractory cancer patients..........Herein, we review ADCs (Antibody drug conjugates) targeting solid tumors, with the focus on 11 programs currently undergoing clinical development....)
"The medical community put a focus on patient safety more than a decade ago, when the Institute of Medicine released a report blaming medical errors for up to 100,000 patient deaths a year.

".....Vision and Goals Vision: We define the prophetic voice as the one that recognizes present realities as they are, reveal to us the error of our ways, predict what may ensue if we refuse to change, and point the way toward a better life for all. We envision a world in which those who are endowed with such a voice and dare to use it openly will be revered and valued members of families, communities, countries and humanity as a whole. That we will learn to listen and learn from such a voice, rather than shun and condemn it. Our project endeavours to make a tangible and creative contribution toward such a world........"

abstract: Mucinous carcinomas of the ovary and colorectum: different organ, same dilemma : The Lancet Oncology
Mucinous carcinomas of the ovary and colorectum: different organ, same dilemma
abstract: Mitochondrial DNA genotyping reveals synchronous nature of simultaneously detected endometrial and ovarian cancers.
AbstractSimultaneous independent primary tumors of the female genital tract occur in 1-2% of gynecological cancer patients, 50-70% of which are synchronous tumors of the endometrium and ovary.
Guidelines for determining the nature of simultaneously detected tumors, based on surgical and histopathological findings, are often ambiguous and may require further molecular analyses.
Such approach is necessary to indicate correct prognosis and hence treatment.
We here demonstrate how mitochondrial DNA sequencing may provide a cheap and useful tool to contribute to indisputably recognize the synchronous nature of simultaneously detected endometrial and ovarian carcinomas. We further confirm our findings by means of Comparative Genomic Hybridization array analysis, which strengthens the informative potential of mitochondrial DNA genotyping in diagnosing synchrony.
abstract: Effects of bevacizumab and pegylated liposomal doxorubicin for the patients with recurrent or refractory ovarian cancers
Currently, pegylated liposomal doxorubicin (PLD) is regarded as one of the standard treatment options in recurrent ovarian cancers (ROC). Bevacizumab has shown significant antitumor activity for ROC in single-agent or in combination with cytotoxic agents. We have conducted a preliminary study to investigate effects of combination of bevacizumab and PLD for heavily pretreated patients with ROC.
The present investigation suggested that combination therapy with bevacizumab and PLD was active and well tolerated for patients with ROC. We recommend the regimen be evaluated in further clinical studies.

abstract: Feasibility of a lifestyle intervention for ovarian cancer patients receiving adjuvant chemotherapy
OBJECTIVESThis study aimed to assess the feasibility of a lifestyle intervention for promoting physical activity (PA) and diet quality during adjuvant chemotherapy for ovarian cancer.
METHODS:Patients were enrolled post-operatively and received PA and nutrition counseling, at every chemotherapy visit for six cycles. Quality of life (QoL) was measured with the Functional Assessment of Cancer Therapy (FACT-G), PA with the Leisure Score Index (LSI), dietary intake with 3-day food records, and symptom severity/distress by the Memorial Symptom Assessment Scale (MSAS). Pedometer step count was collected during chemotherapy cycles.
RESULTS:Recruitment was 73% with 27 patients enrolled. Mean [95% confidence interval] change in minutes of PA from cycle #3 to following cycle #6 was 61min [-3, 120] p=0.063, and from baseline to after cycle #6 was 73min [-10, 15]; p=0.082. Mean change in total fruit and vegetable consumption between baseline and during chemotherapy was 0.56 [-0.09, 0.64]; p=0.090. FACT-G increased from 75.4 at baseline to 77.6 during chemotherapy and 83.9 following chemotherapy (p=0.001 for change from baseline to post-chemotherapy).
Mean total MSAS ( Memorial Symptom Assessment Scale) score was 20.6 at baseline, 26.6 at cycle #3 and decreased to 17.0 following chemotherapy (p=0.01 comparison of cycle #3 and following chemotherapy). Increased moderate to strenuous PA was correlated with higher physical well-being during chemotherapy (r=0.48, p=0.037).
CONCLUSIONS:Lifestyle counseling during adjuvant chemotherapy for ovarian cancer is feasible and may improve PA and diet quality. Randomized controlled trials examining the effects of lifestyle counseling on quality of life and treatment outcomes in ovarian cancer patients are warranted.

abstract: Pyridoxine (Vitamin B6) to protect from oxaliplatin-induced neurotoxicity without compromising antitumour effect
Administration of pyridoxine (Vitamin B6) , at concentrations extending across possible therapeutic plasma levels in humans, does not antagonise OHP (Oxaliplatin) antitumour effects in a range of relevant tumour cell lines.
This study provides a foundation for clinical studies to test whether pyridoxine can minimise OHP-related neurotoxicity, and clinicians can be confident that pyridoxine is very unlikely to reverse the antitumour effects of OHP, as seems to be the case with Ca/Mg infusions.
This could prove to be a cost-effective way to minimise OHP-related neurotoxicity, allowing more effective less toxic treatment and better outcomes in patients.
abstract: Reducing Time to Diagnosis Does Not Improve Outcomes for Women With Symptomatic Ovarian Cancer: A Report From the Australian Ovarian Cancer Study Group

"...Once every few years, we publish a paper that elicits an outpouring of consternation and condemnation from individuals or groups outside our usual reach. The latest topic to have caused such a reaction is chronic fatigue syndrome (CFS), and—more specifically—Peter White and colleagues' randomised PACE trial published on March 5, this year....The response to the trial's publication was swift and damning. “When is the Lancet going to retract this fraudulent study?” demanded a Facebook group. A 43-page complaint (now available via Wikipedia) branded the trial “unethical and unscientific”. There were 44 formal letter submissions, eight of which we publish today, together with a response from White and colleagues." cont'd
"...In the past, medical students were selected on the basis of academic knowledge; it was hoped that traits such as communication skills and sound ethics would develop organically throughout the training process. Now, medical students are increasingly selected on the basis of possession of good social skills—many UK medical schools test prospective students' communication skills, and the USA is considering changing their entrance exam to test would-be students' attitudes. Further, teaching at medical school focuses on the legal, moral, and communication attributes that doctors are expected to have, and this focus continues into a doctor's training years.

MSH6 - Defects in MSH6 are the cause of (Lynch Syndrome) hereditary non-polyposis colorectal cancer type 5 (HNPCDNA mismatch repair protein Msh6 - Homo sapiens (Human)
Defects in MSH6 are the cause of hereditary non-polyposis colorectal cancer type 5 (HNPCC5) [MIM:600678]. Mutations in more than one gene locus can be involved alone or in combination in the production of the HNPCC phenotype (also called Lynch syndrome). Most families with clinically recognized HNPCC have mutations in either MLH1 or MSH2 genes. HNPCC is an autosomal, dominantly inherited disease associated with marked increase in cancer susceptibility. It is characterized by a familial predisposition to early onset colorectal carcinoma (CRC) and extra-colonic cancers of the gastrointestinal, urological and female reproductive tracts. HNPCC is reported to be the most common form of inherited colorectal cancer in the Western world. Cancers in HNPCC originate within benign neoplastic polyps termed adenomas.
Clinically, HNPCC is often divided into two subgroups. Type I: hereditary predisposition to colorectal cancer, a young age of onset, and carcinoma observed in the proximal colon. Type II: patients have an increased risk for cancers in certain tissues such as the uterus, ovary, breast, stomach, small intestine, skin, and larynx in addition to the colon. Diagnosis of classical HNPCC is based on the Amsterdam criteria: 3 or more relatives affected by colorectal cancer, one a first degree relative of the other two; 2 or more generation affected; 1 or more colorectal cancers presenting before 50 years of age; exclusion of hereditary polyposis syndromes.
MSH6 mutations appear to be associated with atypical HNPCC and in particular with development of endometrial carcinoma or atypical endometrial hyperplasia, the presumed precursor of endometrial cancer. Defects in MSH6 are also found in familial colorectal cancers (suspected or incomplete HNPCC) that do not fulfill the Amsterdam criteria for HNPCC. Ref.17 Ref.31 Ref.33 Ref.38 Ref.41 Ref.45 Ref.46

“There are now dozens of studies that demonstrate superior patient outcomes with restrictive transfusion practices,” Dr. Ereth said. “In general, the less blood you transfuse, the better your patient outcomes. In the future we will hopefully be able to further define the mechanisms of immune modulation with transfusion and then when transfusion is absolutely necessary, be able to design interventions to limit those effects.”
Until then, however, he stressed that efforts should be made in all clinical settings to minimize blood transfusion as much as possible.

Science blogger deflates sensationalism of "Scientists cure cancer, but no one takes notice" story - Gary Schwitzer's HealthNewsReview Blog
"....So we have one popular account that is badly written and makes exaggerated claims. There is also a university press release, the source for the sloppy popular account, that doesn't contain the egregious stupidities but does tend to inflate basic research studies into an unwarranted clinical significance. And then, of course, there are the actual peer reviewed papers that describe the research and rationale, and also the reservations, on DCA. It's like a game of telephone: you can actually trace the account from the sober science paper to the enthusiastic press release to the web account with its extravagant claims of a simple, cheap cure for cancer, and see how the story is gradually corrupted. It would be funny if the final result wasn't going to dupe a lot of desperate people.
But there is a germ of truth to the story, in that DCA does have potential.
We should be urging further investigation of this promising drug with the beginning of clinical trials, but it's far too early to be babbling about "cancer cures". There have been lots of drugs that look great in the lab and have excellent rationales for why they should work, but the reality of cancer is that it is complicated and diverse and there are many more pitfalls between a drug that poisons cancer cells in a petri dish and a drug that actually works well in the more complex environment of a human being."
Predicting longevity and curing cancer — quackery, or mere exaggeration? > Facts & Fears > ACSH (re: DCA)
.....In another example of scientific distortion at least bordering on quackery that has infiltrated the media, a Fox News LiveScience blog chastises big pharma for their alleged reluctance to engage in cancer research involving a chemical known as dichloroacetate (DCA), due to their inability to patent it, thereby eliminating the profit motive. The piece chronicles the work of Dr. Evangelos Michelakis, a cancer researcher at the University of Alberta, whose claims that DCA can kill cancer cells are based solely on test tube experiments, animal testing and an extremely small clinical trial he conducted, which was composed of only five patients. Though even he admitted that “with the small number of treated participants in our study, no firm conclusions regarding DCA as a therapy…can be made,” he still attacks pharmaceutical companies for not investing in further research.
But not so fast. As Gary Schwitzer points out on his site, healthnewsreview.org, wherein he links to another blogger’s exposé of the DCA-conspiracy theory, the claims regarding DCA as an effective cancer treatment have been largely exaggerated: since there have been no clinical trials using the chemical, there is no basis for the researchers to allude to a cure.
And even if the claims were true, pharmaceutical companies actually could obtain protection via a “use patent.” This permits patent protection for old products (or drugs) where a new use has been discovered, explains ACSH’s Dr. Josh Bloom. “So this whole story is chock full of misinformation," he observes. "What is more likely is that Dr. Michelakis approached drug companies and they were just not interested.”...."
"......A new drug model
Small trials and case studies won't be enough, however, to prove DCA works. Further investigation into the drug's efficacy is necessary, and without the help of Big Pharma, it will have to happen in an unusual way.
"This could be a social experiment where the public funds these trials," Michelakis said. "After discovering the effect of DCA on cancer cells, I consider this the second-biggest achievement of our work: when we showed that you can bring a drug to human trials without a lot of money. If others were inspired" — his group is beginning to establish collaborations with some prominent cancer hospitals —"this could be a major achievement. Eventually the federal bodies like the National Cancer Institute would see there is enough evidence, and then they'll help with funding."
"It represents a new attitude and a new way of thinking," he added......"

abstract: UK - Hormone replacement therapy and women with premature menopause - A cancer survivorship issue.
AbstractThe importance of addressing survivorship issues has been emphasised in recent years. As cancer therapies improve there is a growing population of cancer survivors, which includes many women with premature menopause. Women who are premenopausal at the time of their cancer diagnosis may have specific survivorship issues to be addressed, including infertility, early menopause and sexual dysfunction. These factors can continue have a significant impact on the quality of life of these patients at long term follow up. Data for this Review were identified by searches of MEDLINE, PubMed, and references from relevant articles using the search terms 'HRT', 'women/female cancer/tumour', 'menopause' and 'survivorship'. Abstracts and reports from meetings were excluded. Only papers published in English between 1980 and 2010 were included.
The aims of this review are to: • Address the hormonal factors which impact on cancer survivorship for premenopausal women • Review the debate for the role of hormone replacement therapy (HRT) in cancer survivors • Provide information for physicians and patients regarding the management of hormonally driven survivorship issues (for different tumour types), based on current evidence
The recommendations for practice are that HRT may be offered for the alleviation of vasomotor symptoms in cancer survivors who undergo premature menopause up to the age of natural menopause (51years in the UK).
HRT (including vaginal oestrogen preparations) is contraindicated in survivors of oestrogen receptor positive breast cancer and low grade endometrial leiomyosarcoma, where non-HRT alternatives should be considered to alleviate symptoms.
DISSERTATIONS.SE: Towards improved management of Lynch syndrome; ovarian cancer profiles, risk perception, knowledge and family perspectives

In summary, we have demonstrated that ovarian cancer linked to Lynch syndrome has distinct genetic profiles, that mutation carriers frequently underestimate their risk of colorectal cancer, possess a good level of knowledge about Lynch syndrome and that families are affected by learning about Lynch syndrome, though few experience adverse effects.

Blogger's Note: this study would apply to all those who experience surgical menopause including those eg. Lynch Syndrome/other Syndromes - women at risk, it is unfortunate that all women undergoing cancer surgery - those affected by surgical menopause were not included in this study
CONCLUSIONS:Women who undergo prophylactic salpingo-oophorectomy prior to menopause experience an increase in vasomotor symptoms and a decrease in sexual functioning. These symptoms are improved by HRT, but not to pre-surgical levels

abstract: MicroRNA let-7a: A potential marker for selection of paclitaxel in ovarian cancer management.
CONCLUSIONS:The study suggests that the beneficial impact of the addition of paclitaxel on EOC survival was significantly linked to let-7a levels, and that miRNAs such as let-7a may be a useful marker for selection of chemotherapeutic agents in EOC management.

Conclusions General population reports on family history for the four major adult cancers were not highly accurate. Efforts to improve accuracy are needed in primary care and other health-care settings in which family history is collected to ensure appropriate risk assessment and clinical care recommendations.
